Ultrasound method for assessing the severity of local wound complications after surgical interventions on the abdominal organs

Abstract

Background. The ultrasound method of examination is often used to detect liquid formations of a postoperative wound. For this reason, the search for new criteria for assessing the course of the wound process is currently relevant. Aim. To study the possibility of using the ultrasound method of research to determine the severity of postoperative wound complications according to the ClavienDindo classification and further optimal tactics, diagnosis and treatment. Material and methods. 255 patients after surgery for various urgent diseases of the abdominal organs, as well as patients with elective surgeries were examined. All patients underwent complex clinical, laboratory and instrumental studies. Continuous values that do not have a normal distribution were processed using non-parametric methods the values were presented in the format Me [Q1; Q3], the difference in unrelated groups was assessed by the MannWhitney U test, and in related groups, by the Wilcoxon test. Results. The postoperative period in 58 (22.7%) of 255 patients was complicated by postoperative wound complications, which had I, II, III severity according to the ClavienDindo classification. On the 5th day of ultrasound examination of the surgical site with the III degree of severity of postoperative wound complications, there was a statistically significant increase in the echogenicity width of tissues in the area of the wound defect compared with the III severity of complications. Conclusion. The ultrasound method of research allows to evaluate the effectiveness of reparative processes in damaged tissues and the development of complications, as well as to determine the severity of their course in the postoperative period for planning further surgical tactics.
